Direct2D Tutorial 2: Showing a Window

In this video we'll look at creating and displaying a main application window. We can't start drawing with DirectX until we've got a window to draw on.

Creating a window is a multistage procedure. We need to register a class for our window, which lets Windows (the OS) know some information about the window, including what function we'll use to process events.

Then we can create our window using the CreateWindow or CreateWindowEX function. Once our window is created we can show it. In the vid I talk about CreateWindowEx, but accidentally call CreateWindow. You want the EX version, I'll fix it next tute.

After our window is shown, we need to start a message loop, which looks for messages from various events occurring with our window. The message loop repeatedly checks if any interactions happen to our window until our window is closed. When we get a message we pass the messages to an event handling procedure we wrote before hand.

It's pretty long winded, but it's not difficult code. One way to do this, is to follow the function and structure pages listed on MSDN. After all, this is Microsoft programming so one of the best resources is the official Microsoft specifications.

There's many resources available which outline what I'm doing in this tute. If you want another explanation, I'd recommend you visit one or both of the following DirectX tutorial websites:
